Why a Computer UPS Can’t Protect Theaters
CIS-NC's Choice For APC and Panamax Line Conditioners
Make sure to select a battery backup specifically designed for AV applications.
Power surges and transients occur in all 50 U.S. states. Blackouts, poorly filtered power, and dirty power can interrupt viewing, erase recordings and lose all of the system’s pre-sets. The recordings stored on your media server or DVR can be lost permanently if power is lost at just the wrong moment.
Satellite receivers and cable boxes can lockup, thereby interrupting service. Expensive light bulbs used in projectors and DLP TVs can be damaged when a blackout occurs.
The right battery backup can protect all of those troubles from happening. Many consumers look to their local mass retailer for one of those small, inexpensive battery backups designed for their home computer. While this might work out OK, there’s a good chance it simply won’t work.
Make sure to select a battery backup specifically designed for AV applications. Here are three reasons AV UPS (uninterruptible power supplies) systems offer better home theater protection.
Handling large components
One major difference is the ability to handle the unique power requirements of larger components. Network file servers and desktop computers typically have an in-rush current draw (the quick, but dramatic amount of current drawn when the device is turned on) of 60-80 Amps for a few milliseconds. Larger components can draw into the 100s of Amps (peak to peak) for several milliseconds on startup.
Computer UPS units are simply not designed to handle this large power draw. This can easily overwhelm the inverter of the UPS, causing it to shut down suddenly and unexpectedly. It is even quite possible for the UPS to be damaged by this overload condition. AV UPSs are designed to handle these large current draws common with big screen TVs and larger amplifiers.
Isolated Noise Filtration
Dedicated isolated noise filtration is another key aspect of AV equipment that is not typically available in computer UPS systems. Electrical Magnetic Interference (EMI) and Radio Frequency Interference (RFI) generally have little impact on computer gear unless its presence is extremely large (and/or the equipment is poorly shielded). For this reason, traditional computer battery backup products contain very small EMI/RFI filters.
If severe enough, EMI/RFI can negatively impact sound and video quality. Properly designed filters, as found in higher-end AV power protection units, can reduce or eliminate this interference so that consumer’s receive the best home theater experience their system can provide.
Too Noisy
Traditional computer UPS systems are too noisy, electrically and audibly, for AV equipment. Light emitting diodes (LED) and visual alarms that are typical of computer UPS systems can also detract from the viewing and listening experience. On the other hand, AV specific models are usually designed to be as quiet and visually unobtrusive as possible.
Audible alarms are “OFF” by default and LEDs can be dimmed or turned “OFF” altogether; similarly, liquid crystal displays (LCD) can be dimmed or turned “OFF”. AV cooling fans are micro-processor controlled with variable speed designed to run only when absolutely necessary.
Furthermore, the industrial design is ideal for placement in home entertainment centers (shelf or rackmount) or AV racks. Also, the UPS batteries are accessible through the front panel so the unit does not need to be removed from the equipment stack.
A true AV-specific battery backup can be a great complement to your system. Knowing you are protected from all the dangers and hassles of today’s unpredictable power grid should give you peace of mind so you can enjoy your home theater experience without interruption.

Sub-$6K Theater Delivers Satisfaction
CIS - Charlotte's Source For Home Theater Installation/Design
This budget-friendly home theater, and its 106-inch screen, provided the finishing touch to a finished basement.
One of the first things Phillip Thomas did after buying his 3,300-square-foot single-family home was finish the basement. He put in a bar, built a bedroom for his college-age son and threw in a nice-size bathroom. But he always felt that something was missing: a home theater.
“At the time, I thought that adding one would blow our budget out of the water,” Thomas says. So he and his family waited. After a few months of saving up, they contacted a local custom electronics professional for a quote. “They had a very firm budget of $10,000,” recalls Jason White of Commtech in Germantown, Md. “It was small, but it gave me some very clear parameters to work with.”
Since the basement was already finished and furnished, all of the money could go toward audio/video equipment and installation. That didn’t mean, however, that White could go crazy with the cash. “I had to be very careful about the products I selected,” he says. Obviously, the price of each component would need to fit the budget. But it was also important that the products chosen could be installed easily and would require minimal programming, White says. Oh, and the equipment would need to perform to the family’s expectations.
One of those expectations was a huge display. “I would settle for nothing less than 100 inches,” says Thomas. Consequently, the largest portion of the budget, $1,000, was allocated to a 106-inch projection screen from Draper. To avoid going over budget, fancy accessories like a motor that allows the screen to roll down from the ceiling were excluded.
A 720p Optoma projector finished off the projection system. Although it lacks the Full HD resolution of a 1080p model, it saved the Thomases more than $2,000. White made sure to run HDMI (high-definition multimedia interface) and extra Category 5 cabling to the projector location “just in case the Thomases ever decide to upgrade,” he says. The entire video setup came in at $2,000, which was about the same price as a much smaller 65-inch plasma or LCD TV.
White also stuck with the basics when it came to the audio/video receiver. The Denon AVR-590 is a quality piece, he says, but with one missing feature: HDMI upconverting. White explains, “A receiver with HDMI upconverting requires just one HDMI cable between the receiver and the projector. With it, any signal from any component will be upconverted to the 720p resolution of the projector.” The “HDMI switching feature” of the AVR-590, on the other hand, required White to route several additional cables from each component to the projector. The switching feature simply allows the signal from the connected source components to pass through to the projector without any enhancement in resolution. It was a minor sacrifice, White says, to save nearly $1,000.
Two fewer speakers would need to be purchased by going with a 5.1 surround-sound setup instead of a 7.1 system, and in-ceiling models would minimize the cost to have them installed.
“It’s usually easier to fish wiring through the ceiling to in-ceiling speakers than go through the ceiling and down the wall to install in-wall speakers because there are fewer obstacles,” says White. “It takes no more than five minutes to install an in-ceiling speaker compared to anywhere between 20 minutes to two hours for an in-wall model.” The 75-watts-per-channel rating of the five Proficient units may be less than the 100-watts per channel of the company’s higher-end units, but the Thomases saved $1,500 by sticking with the mid-grade models.
A final contributor to the savings was a stripped-down control device. The only two source components in the theater are a DirecTV satellite receiver and an upscaling DVD player, so the family didn’t need anything fancy, and so programming the URC MX-900 remote was basic.

Homebuilder Offers Budget Theaters as Optional Amenity
CIS - For All Your Home Theater and Media Room Electronics and Furniture!
This tech-savvy Oklahoma-based builder incorporated a modest home theater into one of his model homes as an example to prospective owners.
Jeff Click of Jeff Click Homes in Oklahoma City specializes in building mid-priced homes, but don’t think of him as your average homebuilder.
For one thing, he embraces technology. His company even does the installation work on simple home theaters in some of his homes. So the logical next step for him was to add a modestly priced home theater to one of his model homes.
“We’ve noticed increasing demand for rooms like this one in modestly priced homes. People are looking for theater rooms, but not the high prices that typically come with it,” Click says.
The builder set out to do an affordable home theater for under $5,000—and he wouldn’t settle for a flat-panel TV hooked up to a receiver and speakers in the family room. No, this is a separate room, about 12 by 18 feet, with a Full HD 1080p front projection system and 5.1 channels of surround sound—and it sells as an $8,450 option on the $245,785 house.
Click also wasn’t content with just filling up the room with audio/video gear and home theater chairs. “We set out to make it unique in style and to accommodate recreation use,” he says.
The soffit surrounding the tray ceiling provides a contemporary splash and lightens the dark room, while a counter in the back row offers raised seating and a place to eat. A wraparound sectional replaces theater-style seats and allows plenty of space in front for Wii games. That’s right: The room is equipped with a Wii game console for family-style fun. Hence the room’s name: Wii-ater room.
Click researched available audio/video gear for his budget. He’s a fan of Denon receivers, so he went with a Denon AVR-587 and added Polk Audio RM7 satellites, two of which are on stands, with the center channel on the equipment console and the two surround speakers mounted on the back wall. No wiring is visible, as electronics installation company Wiring Solutions prewired the room before construction.
But it’s the video system Click is most proud of. It features a 1080p BenQ W1000 DLP projector and a 92-inch gray screen to enhance the DLP’s contrast. “I’m most pleased with the affordable HD projector. It has 1080p resolution and costs around $1,000 to $1,200.
“For our price range and demographic, it’s a little over the top to go with top-of-the-line equipment. [Our buyers] don’t want to have to spend that kind of money,” he says.
That didn’t stop Click from adding an Apple TV system. “I’ve had those since it has come out. We use it like crazy for music or when we miss a show.”
There are some compromises when doing a budget system like this, especially for a model home. For one, he’s got component video cables going into the projector and not HDMI (high-definition multimedia interface). And one thing Click would do over is add an IR (infrared) relay so that someone sitting on the sectional doesn’t have to point a remote backwards to fire up the projector.
